UNITED STATES PATENT A GEEICE,

JOHN W. GENTRY AND GEORGE W. BAROUS, OF PEYTONA, WEST VIRGINIA.

IMPROVEMENT IN CANAL-LOCKS.

Specification forming part of Letters Patent N0. 116,583, dated J nly 4,1871.

To all whom 'it may concern:

Be it known that we, J oEN W. GENTRY and GEORGE W. BARoUs, of Peytona,in the county of Boone and State of West Virginia, have invented a newand useful Improvement in Canal- Locks; and we do hereby declare that,the following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same,reference being had to the accompanying drawing forming part of thisspecilication.

This invention relates to improvements in canal-locks; and it consistsin an arrangement of snubbing-posts or rods in recesses ofthe walls ofthe-locks, whereby the snubbing-ropes may rise and fall on them with theboat in a manner by which the boat may be cont-rolled much better, andthe Wear of the ropes will be less, than in the use of thesnubbing-posts arranged on the top ofthe wall, as in the common way.

Figure 1 is a plan view of a canal -lock with the snubbin g-postsapplied according to our improvements, and Fig. 2 is a longitudinalsection ofthe same.

Similar letters of reference indicate corresponding parts.

A represents the side Yalls ofthe lock, to whicl we propose to Iapplylong rods or posts B, preferably in recesses C in thc said walls, forapplying the snubbingropes D, so that they may rise and fall on the saidposts or rods with the boat, and thereby avoid the tilting and swingingnecessarily due to the irregular action of the snubhing-rope whenworking over the upper edge of the wall upon posts at the top, which hasatendency to tilt the boat when lowering, and prevents, by the frictionof the rope 011 the wall, the tightening up of the ropes sutlicientlywhen rising, and in either case wears the ropes away very fast. Wesupport the rods at the ends in metal plates E, or in any other suitablesupports, and extend them either to the bottom of the lock or tolow-water mark, or thereabout, as may be preferred.

The advantages of this arrangement of the snubbing-rods or posts will beobvious to those acquainted with canal or slack-water navigation.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- In canal-locks, the arrangement ot' long rodsB and supporting-plates E ,in the recesses c of walls A, to act, incombination with the snubhing-ropes l), as and for the purposesspecilied.
